So, I'm finally branching out into getting some pro-level gear. Initially, I wanted to get an Ampeg set-up (SVT-3 pro and 410HLF), because of the name and I've seen a lot of bassists with an Ampeg rig, and I liked the sound. Then I quickly got over that... I played an SVT-7 pro, wasn't too impressed. Not to mention almost every review I've read has stated that their construction just isn't up to standard, whether they're made in America, Korea, or where ever. So I Googled around, and started looking into Genz Benz. I really like the ShuttleMAX 12.2 - 2 adjustable mids, a scoop at 600 Hz, clean amplification. I think it would go well with a Warwick $$ I'd like to get. Plus an Aux-In, which would be perfect to run my Minitaur in. I'm thinking I'd like to run it into two Uber Bass 410 cabs via Speakon cables, sitting relatively beside each other (instead of vertical). I like synths, and I like to use virtual synths to make slow pans with filter sweeps (NOT wah-wah-wah dub step). So I was thinking I'd run my Mac into the parallel 1/4" ins on these cabs, via 1/8" stereo plug split to 2 1/4" mono plugs. So here's my questions: 1) Yep, you guessed it... Ohms. My Macbook audio out is rated at 22 Ohms, but the cabs are only 4 Ohms. Now, I read the 22 Ohms on a forum. But don't the speakers dictate the impedance, not what is supplying the power/sound? 2) Anyone know of a device I could put in between my Mac and the cabs to change the impedance? And lastly... Does this even sound like a good idea to anyone? The idea for me was to have a stereo set-up with enough power to really articulate the psychedelic panning I've made - swimming wall of pressure moving from one side of the room to another. And I was thinking it'd be good to have my own rig, instead of trying to pump it through a PA with everyone else. Thoughts, answers, questions are welcome!
